Solids • They keep their shape • They have mass. • They occupy space.
Properties of Solid Objects Rigid Flexible Smooth Soft Rough Hard Flat Has color Pointed
Liquids • They take the shape of the container that holds them. •You can pour them from one container to another. • •Gravity usually pulls liquid downward. • They have mass. • They occupy space.
Properties of Liquids Bubbly Have color Colorless Flow Foams Pour
Gases • They can float in the air. •Some gases are invisible. • They have mass. • They occupy space.
Properties of Gases They expand to fill their containers Colorless They occupy far more space than the liquids or solids Some are odorless.
Question: How can we prove that gas takes up space?
One property of gas is that it expands to fill its container. If we create gas inside a container, then place a balloon on the container. If gas is created in the container, then the balloon should inflate. Prediction:
Fill a soda bottle with about an inch of vinegar. • Put about a table spoon of baking soda inside the deflated balloon. • Secure the opening of the balloon around the opening of the bottle, then raise the balloon so that the baking soda falls into the vinegar. Plan:
As the gas built up and filled the container, the balloon inflated. Results:
Gas expands to fill a container. Conclusion:
What are the 3 states of matter? Solid Gas Liquid
